TANGEDCO has proposed adding 2 x 660 MW units at the power station - one known as an expansion and the other as a replacement of the now retired power station.
The existing power station was established during 1970-75 in an area of about 237 acres. It had an installed capacity of 450 MW (3x110 MW + 2x60 MW) when commissioned.[1]
The power station was shut down permanently on March 31, 2017, and will be replaced with the proposed 660 MW replacement unit.[2]
New units
Expansion unit
TANGEDCO plans to call for tenders for the construction of a 660MW coal-fired unit (previously 600 MW) in February 2012 with construction scheduled to begin in mid-2012 and commissioning in December 2015.[3][4]
In January 2012 it was announced that Chief Minster Jayalalithaa approved the building of the 600MW coal-fired unit and that it was projected to be commissioned by late 2015. It was reported that the new unit would not require the acquisition of additional land.[3]
The Energy Department's Policy note 2014-15 includes the Ennore expansion (Unit 6). The project cost is Rs 5,000 crore. The construction contract was awarded to Lanco Infratech.[5]
As of April 2015 the power station is listed as under construction by the India government.[6] It is planned for operation in 2018.[7][8]
In March 2018, TNEB cancelled the contract given to Lanco for setting up the unit, saying the project was stuck because of Lanco’s financial problems. Since August 2017, Lanco’s insolvency case is pending with the National Company Law Tribunal. The project was to be commissioned in January 2018, but as of March 2018 is less than 20% complete. According to TNEB, once a new contractor is identified through a re-tender, it would take three more years for the project to be completed.[9]
According to the India Ministry of Power in April 2019, "Corporate Insolvency & Bankruptcy Process (CIRP) [have been] initiated against Lanco (the EPC Contractor) by IDBI Bank from 07.08.2017 and interim resolution professional appointed on 10.08.2017 and hence the project has been stalled from 07.08.2017." No date is offered for completion.[10]
The unit again received environmental clearance on December 11, 2019.[11] It was also announced that month that following the cancellation of the project tender with Lanco, the engineering, procurement and construction contract was awarded to BGR Energy Systems which has said that the overall completion period will be 36 months starting from the date of the contract.[12]
Replacement unit
In addition to the expansion unit, TANGEDCO has proposed replacing the existing 450 MW (nameplate) coal plant with a new 660 MW unit (Unit 7). The company received a terms of reference for the project on July 24, 2014, and submitted an EIA in July 2017.[1]
The plant is opposed by the residents who fear that the new plant will degrade the air quality and lead to a loss of fishing livelihoods.[13]
As of January 2020 there have been no further developments, and the project appears to be deferred or abandoned.
In the 2017 EIA it was reported the new unit would use domestic coal from the Chandrabila coal block, Odisha.[1]
Financing
In 2015, the state-owned Rural Electrification Corporation agreed loan financing for the project of US$890 million.[14] This financing was linked to the first contract for the construction works with Lanco, which was cancelled.
In 2018, it was reported that the Power Finance Corporation provided financing for the expansion project.[9]
